A hybrid approach for solving the gravitational N-body problem with Artificial Neural Networks
Veronica Saz Ulibarrena, Philipp Horn, Simon Portegies Zwart +3
Simulating the evolution of the gravitational N-body problem becomes extremely computationally expensive as N increases since the problem complexity scales quadratically with the n…
Extreme data compression for Bayesian model comparison
Alan F. Heavens, Arrykrishna Mootoovaloo, Roberto Trotta +1
We develop extreme data compression for use in Bayesian model comparison via the MOPED algorithm, as well as more general score compression. We find that Bayes factors from data co…
Almanac: MCMC-based signal extraction of power spectra and maps on the sphere
E. Sellentin, A. Loureiro, L. Whiteway +5
Inference in cosmology often starts with noisy observations of random fields on the celestial sphere, such as maps of the microwave background radiation, continuous maps of cosmic…
